TOOL non REMOVING WHEELS FROM snarrs.

To all whom it mayconcern: 1

Be it known that T, FRANK J. RITzDoRF,.- a citizen of the United States, residing at Dodge, in the county of Dodge and State of Nebraska, have invented new and useful Improvements in Tools for Removing Wheels from Shafts, of which the following is a Specification.

- This invention relates to a tool'designed' primarily for use inremoving wheels from shafts.

The primary object of the invention is to provide-a tool of the class describedin which a follower for contact with the end of the shaft from which the Wheel is to be removed is mounted to slide upon arms on the tool forengagement with the wheel and so arranged with relation to a screw for operat ing the follower that when the device is in use-,theend of the shaft will not be damaged by the turning movement of the screw.

Another object of the invention is to provide a tool of the class described in which a follower for contact' with a shaft from which a wheel is to be removed has formed thereon spaced arms between which are re ceived armson the tool for engagement with the wheel to be removed from the shaft, so

that when a screw upon the tool is opera--" tively engaged with the follower an even pull is exerted upon the wheel on the shaft thus preventing said .Wheel from bindlng as the shaft is forced through the same by means of the tool.

'35 With these and other objects in view, the invention resides in the novel combination and arrangement of parts, which will be hereinafter described and particularly point ed out in the claims.

The preferred embodiment of the invention has been illustrated in the accompanying drawing, although no restriction is necessarily made to the precise details of construction therein shown, as changes, altera- 4 tions, and modifications within the scope of the claims may be resorted to when desired.

Like characters of reference denote corresponding parts throughout the several vlews in the drawing, in which:

lFigure 1 is 'a side elevation of a tool for the purpose set forth constructed in accordance with the invention and showing the same in position upon a shaft for removing a wheel thereon. .Fig. 2 is a horizontal transverse sectional view on the line 2+2 of Fig. 1 showing, the tool removed from the shaft. Fig. 3 is a vertical transverse sec- Specification of Letters Patent.

tional view on the line 3-3 of Fig. 1 show-- ing the tool removed from the shaft. Fig.

4 is a detail perspective view of one of the operating the follower and designated by the numeral 6. The head 3 is formed from a bar 7, having an enlargement8 between its ends provided with a longitudinally extending andthreaded opening 9, said bar .beted upon opposite sides, as at 10 a longitudinally extending tongue ll having a row of spaced openings 12 therein near each end. Thescrew 6 has a threaded shank 14 mounted to'turn inthe opening 9 in the enlargement 8 in the head 3, said shank being reduced for a portion of its length near one end to provide a stud 15. co-acting with the shank in forming av bearing shoulder 16 near one end of the shank. The other end of the shank 14 which extends above the head 3 is provided witha head 17 having a plurality of angular faces 18 adapted to receive a wrench or the like when it is desired tov impart turning movement to the screw.

The arms 4 which are substantially triangular in shape in cross section for the greater 1 portlon of their length are arranged at the respective ends of the head 3 and pivotally I connected therewith by means of spaced ears tion with the wheel upon the shaft whensaid wheel islocated a distance from the end of the shaft greater than the length of the arm 4. I

The flared heads'on the arms 4 prevent the follower 5 fromsliding off of the arms 4 when the tool is not in use and each extenvsion 21 may have connected therewith an arm similar to the arms 4 when it is desired to increase the length of said arms and the use of the hook and chain is not desirable.

' The follower'.5

which is a recess 23 adapted to receive the biting rab- I to provide comprises a substantially rectangular shapedblock 22 in one'face of stud 15 on the shank 14 of the screw 6, the

other face of the block being provided with a centrally arranged and cone-shaped hearing stud 24 having the pointed end thereof arranged to contact with the shaft upon which is mounted the wheel to be removed by means of the tool. Plates 25 are arranged upon opposite sides of the block 22 and secured thereto between their ends by means of bolts 26 passing through said plates and the block 22. The plates 25 co-act'with the block 22 in providing arms 27 each of which has formed therein a longitudinally extending slot 28.

Sleeves 29 are arranged between the portion of the plates 25 which form the arms 27 and between which, are received the arms 4 connected with the head 3, said sleeves having passing therethrough screws 30 which are'also received in the slots 28 in the arms 27 and are provided with thumbnuts 31 by means of which the sleeves whenbeneath therim of the wheel to be removed.

The screw 6 is nowadjusted within the head until the bearing stud 24 on the follower can be positioned upon an end onthe shaft.

The thumb-nuts 31 are tightened after the heads 20 have been positioned beneath the rim o f the wheel and with the parts in this position a wrench may be engaged with the head 17 on the screw 6 and said screw turned to move the follower toward the heads 20 on the arms 4.

By providing the block 22 with the recess 23 in which is received the stud 15 shifting of the follower while the device is in use is prevented, while the shoulder 16 insures the shank of the screw bearlng firmly upon the block22 above the bearing stud 24- which prevents the shaft from becoming marred or damaged by theturning action of the screw 6. I

It will be noted with reference to Fig. 3

I in the drawing that the arms 4 are substantially' triangular in shape in'cross section,

so that .when the wheel to be removed from the shaft is a gear wheel, the arms may be positionedbetween the teeth thereon and in this manner be prevented from any tendency to cause the wheels to bind on the shaft, such binding action being prevented when the wheel has a plain rim by the arms on the follower 5.

Through the provision of the spaced openings, in the tongues 11 the arms 4 may be adjusted longitudinally of the head 3 to allow the tool to be used upon wheels which vary in diameter.

From the foregoing description, taken in connection with the accompanying drawing, it is at once apparent that a tool for removing wheels from shafts has been provided which though simple of construction is eX- tremely strong and durable in use.

Having thus described the invention, what is claimed as new is: 1. A device of the class described comprising a head, arms adjustablv connected with the head, a screw mounted to turn in said head and extending below the same'between the arms, and a follower mounted to slide on said arms and adapted to contact with said screw. v

2. A device of the class described comprising a head rabbeted to provide a tongue, arms pivo-tally connected with said tongue, a screw mounted to turn in said head and reduced for a portion of its length near one end to provide a stud. and a follower mounted to slide on said arms and having a recess to receive said stud.

3. A device of the class described comprising a head rabbeted upon opp site sides to provide a tongue, arms pivotallv connected with said tongue and substantiallv triangular in shape in cross section for the greater portion of their length, a screw mounted to turn in said head and reduced for a portion of its length near one end to provide a shoulder, a follower mounted to slide on said arms and including a block for contact with said shoulder, and a bearing stud on the under-face of said block for contact with a shaft.

4. A device of the class described comprising a head, a screw mounted to turn in said head, a block for contact with an end on said screw and having a bearing stud for engagement with a shaft, plates arranged upon opposite sides of said block and having slots therein, arms connected with said head and received between said plates for engagement with a. wheel upon a shaft, sleeves interposed between said plates in advance of said arms, bolts passing through the slots in the plates and sleeves, and thumb-nuts adjustably ,mlounted upon said bolts and bearing against isaid plates.

In testimony whereof I afiix my signature.
